5*x-7 = 0
5*x-7 = 0
5*x-7 = 0
5*x-7 = 0 // + 7
5*x = 7 // : 5
x = 7/5
x in (-oo:7/5) U (7/5:+oo)
(2*x+1)/(5*x-7) = 3/4 // - 3/4
(2*x+1)/(5*x-7)-(3/4) = 0
(2*x+1)/(5*x-7)-3/4 = 0
(4*(2*x+1))/(4*(5*x-7))+(-3*(5*x-7))/(4*(5*x-7)) = 0
4*(2*x+1)-3*(5*x-7) = 0
25-7*x = 0
(25-7*x)/(4*(5*x-7)) = 0
(25-7*x)/(4*(5*x-7)) = 0 // * 4*(5*x-7)
25-7*x = 0
25-7*x = 0 // - 25
-7*x = -25 // : -7
x = -25/(-7)
x = 25/7
x = 25/7
